Innovating product design is crucial for firms operating in the digital sector as it is closely linked with innovation capability and, therefore, with firm performance and productivity. In this paper, we run a randomized controlled trial to assess if participating in an open innovation initiative increases SMEs’ capability to design more competitive digital products. More specifically, the intervention aimed at increasing firms’ knowledge of the Design Sprint and their readiness to implement user-centered design techniques.

Science funding agencies such as the NIH, NSF, and their counterparts around the world are often criticized for being too conservative, funding incremental innovations over more radical but riskier projects. One explanation for their conservatism is the way the agencies use peer review of scientific proposals. Peer review is the cornerstone of research allocation decisions, but agencies typically base decisions on a simple average of peer review scores. More novel ideas are less likely to gain consistently high ratings across evaluators and are less likely to be funded.

This experiment involved making the information on the WBSO website clearer and more personally relevant to entrepreneurs. The visibility of the call-to-action was also enhanced. The study showed that entrepreneurs were prompted to spend more time exploring the possibilities offered by the Research and Development (Promotion) Act (WBSO) and that they read the information more carefully.

This experiment is listed in the BINN report "A wealth of behavioural insights - 2023 edition". Further information on the trial and authors may be available elsewhere.

Drawing the attention of innovators to climate change is important for green innovation. We report an email field experiment with MIT using messages about the impact of climate change to invite innovators (SBIR grantees) to apply to a technology competition. We vary our messages on the time frame and scale of the human cost of climate change across scientifically valid scenarios. Innovator attention (clicks) is sensitive to climate change messaging. These changes in clicks also predict higher application rates.

Innovation plays a pivotal role in fostering economic growth, yet there is a limited understanding of whether it can be taught. I conduct a randomized evaluation of an education program implemented by a state government and a nonprofit organization, providing an opportunity to 6,224 8th-grade students from disadvantaged backgrounds to develop frugal innovations for global and local problems. To assess students’ innovative ability, I created a novel scale with inputs from experienced inventors and used a lab-in-the-field game from experimental economics.

Understanding how to design policies to effectively reduce firm-level carbon emissions while minimizing impacts on economic growth is a question of central importance in the battle to mitigate climate change. The EU is proposing a Carbon Border Adjustment Mechanism (CBAM) that will tax imports to better reflect their carbon content. This project evaluates three policies that provide firms with training and assistance obtaining loans with the goal of mitigating the impacts of CBAM on Turkish SMEs.

An RCT was used to investigate the effectiveness of an innovation support scheme (ISS) for SMEs in tackling age diversity challenges. The ISS included leadership training aimed at fostering team climate and valuing age diversity, and computer-based cognitive training for employees. Levels of recruitment into the trial, engagement in the interventions and response rates to surveys were lower than anticipated, which have all limited the potential to identify the impacts of the interventions.

We examine the influence of physical proximity on between-startup knowledge spillovers at one of the largest technology co-working hubs in the United States. Relying on the random assignment of office space to the hub's 251 startups, we find that proximity positively influences knowledge spillovers as proxied by the likelihood of adopting an upstream web technology already used by a peer startup.

Resource allocation decisions play a dominant role in shaping a firm’s technological trajectory and competitive advantage. Recent work indicates that innovative firms and scientific institutions tend to exhibit an anti-novelty bias when evaluating new projects and ideas. In this paper, we focus on shedding light into this observed pattern by examining how evaluator expertise in the problem’s focal domain shapes the relationship between novelty and feasibility in evaluations of quality for technical solutions.

Women are underrepresented in patenting and the gap is not closing quickly. One major roadblock to progress is a dearth of causal evidence on the potential effectiveness of policies to reduce the gender gap in patenting. Analyzing a randomized control trial at the United States Patent and Trademark Office that was designed to provide additional help to applicants who do not have legal representation, we find heterogeneous causal impacts across gender and technologies on the probability of obtaining patent rights.

Design thinking remains mired in controversy. Its proponents claim that it enhances not just confidence but also creativity, while the opponents question whether it does anything beyond building unfounded confidence. To bring rigorous evidence to this debate, we designed a randomised field experiment amongst school children served by a major non-governmental organisation in rural India.

We examine how the behavior of software developers changes in response to removing gamification elements from GitHub, an online platform for collaborative programming and software development. We find that the unannounced removal of daily activity streak counters from the user interface (from user profile pages) was followed by significant changes in behavior. Long-running streaks of activity were abandoned and became less common. Weekend activity decreased and days in which developers made a single contribution became less common.

Cavendish Enterprise's Business Boost trial project involved providing young small firms - typically micro-businesses - with a treatment involving a series of workshops designed to enhance productivity. This was provided largely as a top-up to an advice and mentoring programme called 'Start and Grow'. The project was part of the government's Business Basics Programme which has the core aim of identifying cost effective, yet productivity enhancing, programmes of business support for SMEs which can be run at scale throughout the country.

The main objective of this project is to test the effects of feedback with and without relative ranking scores on SMEs and first-time applicants performance in the funding program “General Programme” of the FFG, and business performance after the program. The feedback for each firm will be based on evaluations scores of the respective funding proposal from project evaluators in the FFG. The participants in the RCT are all Start-ups, SMEs, and large companies who are first-time applicants accepted into the funding program in the timespan of a year.

We investigate how knowledge similarity between two individuals is systematically related to the likelihood that a serendipitous encounter results in knowledge production. We conduct a field experiment at a medical research symposium, where we exogenously varied opportunities for face-to-face encounters among 15,817 scientist-pairs. Our data include direct observations of interaction patterns collected using sociometric badges, and detailed, longitudinal data of the scientists' postsymposium publication records over 6 years.

Many Start Ups and Small & Medium Enterprises (SME) have an immature methodological approach to innovation and half of them present a clear deficit in innovation know-how, pointing towards a need for extra support. The efficacy of two approaches to building knowledge and increasing awareness of non-technical innovation among Start Ups and Small and Medium Enterprises (SME) will be tested.

Organizations constantly strive to unleash their entrepreneurial potential to keep up with market and technology changes. To this end, they engage employees in practices like corporate crowdsourcing, incubators, accelerators or hackathons. These organizational practices emulate independent “green-field” entrepreneurship by relinquishing hierarchical control and granting employees autonomy in the choices of how to conduct work.

Individual-level opportunity recognition processes are vital to corporate entrepreneurship. However, little is known regarding how managerial communication impacts the effectiveness of idea suggestion systems in stimulating individuals' participation in intrapreneurial ideation. Integrating self-determination theory, creativity, and framing research, we theorize how different ways of inviting employees to submit proposals (opt-out/opt-in registration; provision of examples) affect the number and quality of submitted ideas.

User entrepreneurs are responsible for the most important innovations in many industries, but little research has explored the performance of firms founded by user entrepreneurs. While user entrepreneurs have a deep knowledge of customer needs that facilitates the identification of innovative solutions, they tend to lack the relevant business knowledge (e.g., market, production, operational and organizational) to successfully exploit opportunities and grow their ventures.

In 2004 and 2005, the then Ministry of Economic Affairs issued innovation vouchers to SMEs to promote cooperation and knowledge exchange between companies and knowledge institutes in the field of innovation. The underlying idea was that more new products, services and/or processes can be developed with more knowledge exchange. This innovation can in turn lead to an increase in turnover and productivity, which ultimately leads to more prosperity.

We design two laboratory experiments to analyze the causal effects of competition on step-by-step innovation. Innovations result from costly R&D investments and move technology up one step. Competition is inversely measured by the ex post rents for firms that operate at the same technological level, that is, for neck-and-neck firms. First, we find that increased competition leads to a significant increase in R&D investments by neck-and-neck firms.

As the largest encyclopedia in the world, it is not surprising that Wikipedia reflects the state of scientific knowledge. However, Wikipedia is also one of the most accessed websites in the world, including by scientists, which suggests that it also has the potential to shape science. This paper shows that it does. Incorporating ideas into Wikipedia leads to those ideas being used more in the scientific literature.

Existing theories and empirical research on how innovation occurs largely assume that innovativeness is an inherent characteristic of the individual and that people with this innate ability select into jobs that require it. In this paper, we investigate whether people who do not self-select into being innovators can be induced to innovate, and whether they innovate differently than those who do self-select into innovating.
